$RGC Loading for a breakout!! Regencell takes this theory behind TCM a little further and the company notes that their TCM formulas are derived from a TCM base formula plus an adjustable formula developed by Regencell’s strategic partner, TCM practitioner, Mr. Sik-Kee Au, based on his TCM brain theory. The TCM brain theory explains why a healthy brain is essential in restoring the body’s systems to normal. According to the TCM brain theory, the blockage of or reduced blood flow, and damage of the interconnecting central nervous system, endocrine system and blood circulatory system disrupt the production of hormones and transmission of neurotransmitters, such as melatonin, dopamine, and norepinephrine, leading to a defective encoding and decoding of functions, and resulting in deficient or abnormal social behaviors that are the hallmarks of ADHD and ASD.
